通常,如果你要找的刚刚ESTALISHED的那个PCB,是在tcp_echoserver_accept中传递进来的,在下面的代码中,就是这个, pcb = tcp_echoserver_es->pcb; 第二点 接收完数据后,调用tcp_recved扩大窗口。tcp_recved函数中,最关键的代码是 pcb->rcv_wnd += len; ...

IP provides addressing and routing functions for end-to-end delivery. In 1982, the Defense Communications Agency (DCA) and ARPA established the Transmission Control Protocol (TCP) and Internet Protocol (IP) as the TCP/IP protocol suite. In 1983, ARPANET switched from NCP to TCP/IP...
